Struct DefaultJitter 

pub struct DefaultJitter { /* private fields */ }

Production Jitter: a tiny, hand-rolled SplitMix64 PRNG (no external dependency).

Seeded once at construction from a one-time nanosecond clock sample XORed with a monotonically advancing process counter; each jitter01 advances the 64-bit state and maps the top 53 bits to a [0, 1) double. SplitMix64 is the standard seeding PRNG (it is what rand’s SeedableRng::seed_from_u64 uses internally) and is more than adequate for jitter — this is decorrelation, not cryptography.

Interior mutability (AtomicU64) lets jitter01 take &self (matching the trait) while still advancing the stream, so a single instance can be shared across the retry loop.

Implementations

impl DefaultJitter

pub fn new() -> Self

Builds a jitter source seeded from the current nanosecond clock XORed with a process-wide counter (so concurrent constructions diverge).

Trait Implementations

impl Debug for DefaultJitter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DefaultJitter

fn default() -> Self

Returns the “default value” for a type.

impl Jitter for DefaultJitter

fn jitter01(&self) -> f64

Returns the next jitter fraction in [0, 1).
